To all w/io'm it may concern:

Be it known that I, FREDER CK l3. MILLER, a citizen of the United States, residing at hcottdale, in the county of lVestmoreland and State of Pennsylvania, have invented certain new and useful Improvements in Screen-Fabricatinc Machines of which the following is a full, clear, and exact specification.

My invention relates to improvements in screen-fabricating machines in. which parallel rotating shafts have a plurality of rolls operating in conjunction with a carriage for interlocking warp members wlth weft members; and the objects of my improve- Fig. 1, is a plan view of a fabricated screen.

Fig. 2, is an end view of fabricated screen.

Fig. 3, is a longitudinal sectional view of the machine taken in the plane of line 22 of Fig. 4, showing screen secured in carriage, which operates in conjunction withthe revolving rolls for interlocking warp members with weft members.

Fig. 4, is an end elevation of the machine emboding my invention.

Fig. 5, is an elevation of shafts, gears and rolls, by means of which adjacent warp members are bent opposite.

Fig. 6, is an end view of shafts, gears and rolls.

The various novel features of my invention will be apparent from the description and drawings, and will be particularly pointed out in the appended claims.

While this invention finds application to machines for fabricating screen, the invention is not limited to such machines and to such fabrication.

The bed 10, and the journal frames 11' secured to the bed, constitute the frame work of the machine. In the journal frames 11, the shafts 12 13 turn in opposite direction by reason of the gears 14 14. The shafts 12 13 rotated by the gear-wheel 15 are provided with a plurality of rolls 16, arranged on the said shafts, so that the rolls on the shaft13. iTlie basalcarriage 117 fed-by the screws 18,18 is provided with-bearing surfaceslg 1:9, adapted. to; 'slide on guides'20 .20. The screws 18 .18 turned by the shaft mares shatt12 will bet-ween,; t he; rolls on p 13, by means of; thesprockets .2122, chain,

23, shafts and gears 25 26, areprovided thrust bearing surfaces 27 27 and, bearings 28 28, so that the screws 18 18 threaded for the reception of thefemal'e screws 29.29 in carriage 17, will move the said carriage on.

the guides 20 20. The carriage 17 has a de' pression 30 for proper alignment of the warp members 31, which are secured to the carriage by a clamp bar 32 and clamp screws From the construction and arrangements of parts shown and described, it is obvlous that the adjacent warp members 31 arefbent oppositely sufficiently by reason of contact with the revolving rolls 16, to form ashed to receive a weft member 34. The carriage having'ad'vanced one crimp of the longi tudinal rod 31, the following rolls 16 come in contact, and bend the warp members, in-

terlocking a weft'member with warp'members. The operation. is repeated to makeup the weft members of thescreen.

There may be many modifications of the invention other than here shown and described and it is my intention to cover all j such modifications which do not involve a] departure from the spirit and scope of my 9,

invention as claims.

What I claim as new is: 1. In a machine of the character deset forth in the appended scribed, a bed, journal frames secured to said bed, parallel shafts mounted insaid journal frames, rolls on one shaft eccentric with respect to said shaft and alternately disposed in opposite directions to roll alternate'warp members, rolls on the other shaft eccentric with respect to said shaft and alternately disposed in opposite directions, said rolls staggered with respect to the rolls on the first mentioned shaft to roll alternate warp members from the opposite side, said rolls adapted to revolve in opposite directions to,

opposite directions to form a shed to receive weft members, feeding mechanism associated with the rolls for advancing the warp members in step with said rolls.

2. In a machine of the character described, in parallel shafts between which warp members efi'ect bending of adj acentwarp members in are "fed, rolls on one shaft eccentric with re spect to said shaft and alternately disposed in opposite directions to engage alternate Warp members, H rolls on the other shaft eccentric With respectto said shaft and a1- ternately disposed in opposite directions,

said rolls staggered with respect to the rolls on the first mentioned shaft to engage alter nate Warp members from the opposite side, rolls adapted to 11511 Warp members to ellffeet bending of aeent Warp members in "01 'osit'e' directions to form a shed to re was nienihers', feeding mechanism as s'oclated Wlth the rolls for advancing the war-p Inemhers' in step with said rolls, in-

neaaoee eluding a sprocket fixed to one Of said par ailel shafts, a jack-shaft, a sprocket fixed to said jack-shaft, a chain connecting said sprockets. a screw-shaft, a pair of engaged miter-gears fixed to said screw-shaft and said 20 jackshaft, a carriage actuated by said screw-shaft, and a clamp bar for clamping the iahrlc to the carriage.
